# like some performance data against a big database first - might cause problems?

# (can be used during search). Need join in addition to the eagerload since it is used in
# the .count() query which doesn't respect the eagerload options (could eliminate this with #5523).
# - Undefer average_rating column to prevent loading individual ratings per-history.

# potentially many items per history (like if joining HDAs for instance) but there should only
# be at most one so this is fine.
